Answer

Explanation:

Step1: Identify reaction in question 8

The diagram shows a large nucleus splitting into smaller nuclei and releasing neutrons, which is characteristic of fission.

Step2: Balance the equation in question 9

For the equation $^{235}{92}U + ^{1}{0}n\rightarrow^{142}{56}Ba+^{91}{36}Kr + 3X+ \text{energy}$, balance mass - number and atomic - number. Mass - number: $235 + 1=142 + 91+3\times A$, where $A$ is the mass - number of $X$. Solving gives $A = 1$. Atomic - number: $92+0 = 56+36 + 3\times Z$, where $Z$ is the atomic - number of $X$. Solving gives $Z = 0$. So $X$ is a neutron $^{1}_{0}n$.

Step3: Recall fusion reaction in question 10

Fusion is the combination of two light nuclei to form a heavier nucleus. The reaction $^{2}{1}H+^{2}{1}H\rightarrow^{4}_{2}He$ is a fusion reaction.

Step4: Recall fission reaction in question 11

Fission is the splitting of a large nucleus into smaller nuclei. The reaction $^{235}{92}U+^{1}{0}n\rightarrow^{92}{35}Br + ^{141}{57}La+3^{1}_{0}n$ is a fission reaction.

Answer:

  1. a) Fission
  2. a) $^{1}_{0}n$
  3. c) $^{2}{1}H + ^{2}{1}H\rightarrow^{4}_{2}He$
  4. c) (assuming the correct fission - like reaction is intended as the one with uranium splitting)
